ERROR 1129 (00000): Host 'XXXXXX' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'
         查了下资料
         这说明mysqld已经得到了大量(max_connect_errors)的主机'hostname'的在中途被中断了的连接请求。在 max_connect_errors次失败请求后，mysqld认定出错了(象来字一个黑客的攻击)，并且阻止该站点进一步的连接，直到某人执行命令 mysqladmin flush-hosts。
缺省地，mysqld在10个连接错误后阻塞一台主机。你可以通过象这样启动服务器很容易地调整它： set global max_connect_errors=1000;
注意，对给定的主机，如果得到这条错误消息，你应该首先检查该主机的TCP/IP连接有没有问题。如果你的TCP/IP连接不在运行，增加max_connect_errors变量的值对你也不会有帮助！

例:

/usr/local/mysql/bin/mysqladmin flush-host -h 192.168.50.1 -uroot

附：英文

ERROR 1129 (00000): Host '' is blocked because of many connection errors. Unblock with 'mysqladmin flush-hosts'

If you get the following error, it means that mysqld has received many connect requests from the host 'host_name' that have been interrupted in the middle:
